#3 Alexis Sanchez – Arsenal to Manchester United (2018)

Perhaps the only positive that can now be said about Alexis Sanchez’s move from Arsenal to Manchester United in January 2018 is that the Red Devils at least didn’t pay a transfer fee for him; in a rare straight swap, the Chilean headed to Old Trafford with Armenian midfielder Henrikh Mkhitaryan heading the other way.
Sanchez had been one of the Premier League’s most dynamic attackers at the Emirates, scoring a total of 60 goals for the Gunners in just 122 league appearances and providing plenty of assists, too. But if United had been expecting the move to work out in a similar fashion to that of Robin Van Persie – who moved from Arsenal to Old Trafford in 2012 – they were sorely mistaken.
It’s still hard to put a finger on quite what went wrong for Sanchez at United; handed a bumper contract that paid him £400,000 per week, it was as if the Chilean simply couldn’t be bothered at times, and he barely resembled the player he’d been at Arsenal. By the time 2017-18 ended with him scoring just 3 goals for his new club, it felt written in stone that he’d go down as an all-time bad transfer.
Sanchez continued to struggle in his second season at Old Trafford, failing to make an impact under both Jose Mourinho and his replacement Ole Gunnar Solskjaer. When he moved to Inter Milan on loan in the summer of 2019, it felt like a millstone had been removed from the Red Devils’ neck.
